7.2 Lubricating the product
7.2.1 Lubricating the motor
Always follow the motor manufacturer's lubricating instructions, if
they are available, and periodically check grease fittings and
drain plugs for leaks. If the lubricating instructions are not
available, refer to the table below for recommended lubricating
intervals.
• The motor can be lubricated both when it is running or when it
is stopped.
Remove the grease drain plug, if any, and filler plug on the
grease fitting. Grease with clean lubricant until grease
appears at the drain hole or along the motor shaft.
One-half to one cubic inch (0.5
3
- 1
3
inch) of grease is sufficient
for motors of 4 kW and lower, with proportionately more grease
for bigger kW motors.
Most fractional and some integral frame motors have
"sealed-for-life" bearings, and do not require further lubrication
throughout motor life.
The table Approved grease lubricants in section 7.2.2 Lubricating
the pump lists the recommended types of grease for both pump
and motor lubrication. These grease types have all been
thoroughly tested and must be used whenever possible.
